Coupling of in-situ Sm-Nd Systematics and U-Pb dating of monazite and allanite with applications to crustal evolution studies

McFarlane, Christopher; McCulloch, Malcolm


Here we demonstrate the capabilities of LA-MC-ICPMS Sm-Nd-isotope measurements applied to two of the most common LREE-enriched minerals in the Earth's crust: monazite and allanite. We show that high precision measurements of143Nd/144Nd comparable to solution-based MC-ICPMS measurements (< 0.5 epsilon units) can be achieved for laser spot sizes ranging from 16 to 50 μm. At this scale, sub-grain domains previously dated using in-situ U-Th-Pb geochronology (e.g., ion-microprobe) can be...[Show more]
